This medication should not be used by patients allergic to specific ingredients or those who have previously exhibited hypersensitivity to hydroxizine or piperazine derivatives. It should not be administered to patients with very poor kidney function or those undergoing dialysis, and should not be used in infants under 1 year old. For children under 6 years old, it is safer to administer the liquid form rather than tablets. The tablet contains lactose; therefore, it should not be used in patients with lactose intolerance or related genetic disorders. Patients with impaired kidney or liver function, and elderly patients should use this medication with caution as it may be maintained at higher concentrations in their systems. This medication may cause neurological symptoms such as drowsiness, fatigue, headache, and dizziness, along with gastrointestinal symptoms like indigestion, nausea, and abdominal pain. Rarely, symptoms such as heart rhythm disturbances, changes in blood cell counts, allergic reactions, and blurred vision may occur, and if symptoms are severe or persistent, it is advisable to consult a doctor. Care should be taken when driving or operating machinery after taking this medication as drowsiness or reduced concentration may increase the risk of accidents. Combining with alcohol or central nervous system depressants may exacerbate drowsiness or decreased concentration, hence it is better not to take them together. Patients with urinary excretion disorders may experience aggravated symptoms when taking this medication, thus it should be used cautiously. Patients with epilepsy or those at risk of seizures should be cautious as their symptoms may worsen after taking this medication. Pregnant women should consult a doctor before use due to a lack of clear data on the impact of this medication on the fetus. Breastfeeding women should use caution as this medication may be excreted in breast milk, possibly causing adverse reactions in infants. This medication is mainly excreted through the kidneys; hence elderly patients with reduced kidney function should start at a low dose and be closely monitored. Before undergoing allergy testing, it is advisable to discontinue this medication temporarily to enhance the accuracy of the test. In the case of overdose, symptoms such as drowsiness, agitation, and restlessness may occur, and as there is no specific antidote, symptomatic treatment should be administered. This medication is not significantly removed by dialysis, thus alternative treatment methods should be used in the event of an overdose.
